Patient discussion about stiffness

Q. can acupuncture help neck stiffness? I have neck pain- especially stiffness every week- once or twice. Try a lot of things but always comes back. Can acupuncture help? tell me please because if not- I dont want to put needles for nothing...

A. Acupuncture can fix most cases of neck pain, usually in 3-5 treatments. Most neck pain is due to muscular tightness, and acupuncture is very effective at releasing contracted muscles.

here's an article on Acupuncture for Back Pain:

The treatment of neck pain is very similar. There are very few cases of side effects with acupuncture. However, if you experience consistent pain that get progressively worse, you should visit your MD for x-rays and an MRI to rule out any structural problems (bone spurs, disc degeneration, tumors, etc).

Q. I received a corticosteroid injection in my left knne th A.M. Knee is all stiff & swollen. Is this normal?

A. actually you might have already had an arthritis in your knee before, then your doctor injected you with a corticosteroid into the affected joint. usually you will feel better (less pain) in your affected joint. if the symptoms don't improve then I suggest you to go see your specialist for further advise and treatment.

Q. i cant stop getting a hard on erection stiffy embarrassing crease in trousers

A. Have you heard of priapism,a condition in which the penis is continually erect; usually painful and seldom with sexual arousal. If you suffer from this you should go see a doctor about it.
